G0>'OLABIS. 70 



This species is known only through Dubrouy's description. 

 It is recorded from the Ply Eiver, New Guinea. An immature 

 specimen in the Indian Museum, from Tavoy, is attributed to it, 

 with considerable hesitation. 



Genus GONOLABIS, 5nrr. 



Gonolabis, Burr, (00") pp. 48 & 53; Borjn. (00') p. 451; Ei'rbi/r 

 (04) p. 15. 



Type, Anisolabis javana, Bormans. 



Entii'ely apterous. Antennae ^\•ith less than 20 segments, third 

 cylindrical, fourth and fifth globular, the rest longer, subpyriform. 

 Head smooth. Pronotum square, as broad as the head or broader. 

 Sternal plates as in Anisolahis. Elytra entirely wanting. Femora 

 rather thick ; tibiae and tarsi compressed, the latter very slender; 

 second segment very short. Abdomen in the c? narrow at the 

 base, gradually broadened, attaining the greatest width at the apex. 

 Last dorsal segment of the c? broad and rectangular ; of the 5 

 broad, but narrowed posteriorly. Forceps of the c? stout, remote 

 at base, arcuate strongly ; of the $ conical, contiguous, straight. 



Range. Asia, Africa, Australia. 



By the removal of certain non-Indian species, characterized by 

 a strongly narrowed prosternum, this genus is now restricted to 

 Old World forms. The genus is related to Anisolahis, but has 

 fewer antennal segments ; the gradual widening of the abdomen 

 from base to apex is very characteristic. 



36. Gonolabis electa, sp. n, (Fig. 21.) 



Small ; shining dark chestnut-brown. Antennae brown, basal 

 segments paler, with 14-15 segments; third cylindrical, elongate, 

 fourth and fifth globular, the rest gradually lengthening, passing 

 from subcylindrical to ovate. Head tumid, smooth, shining, dark 

 blackish brown. Pronotum as broad as the head, square or very 

 gently widened posteriorly, flat, shining brown, the sides paler. 

 Mesonotum short, about t^vice as broad as long. Entire thorax 

 smooth, shining, deep brown. Legs testaceous, femora with darker 

 shading. Abdomen of the same colour, gradually dilated in the c? 

 from the base to the apex, which is about 1| times as wide as 

 the base. Sides of the sixth to ninth segments produced back- 

 wards to sharp points in the S only. Last dorsal segment : in 

 the <S rectangular and about twice as broad as long, smooth and 

 shining, with a faint median depression, posterior margin trun- 

 cate ; over the roots of the forceps there is a slight tumid 

 elevation, outside which is a depressed triangular area, so that 

 the segment is bounded externally by a slight longitudinal fold or 

 ridge which is continuous with the line formed by the points of the 

 sixth-ninth abdominal segments ; in the $ trapezoidal, strongly
